On Saturday night, the "Sorry Not Sorry" singer—a Disney Channel sitcom star-turned-chart-topping bubblegum chanteuse—will climb into the ring at Las Vegas's T-Mobile Arena to belt out the national anthem in advance of the so-called "Money Fight." That is, the non-title bout between Gucci fur coat-wearing McGregor (UFC champion in two separate weight divisions) and undefeated boxing legend Mayweather (coming out of retirement at age 40) that's expected to become the most profitable pay-per-view event in the history of pay-per-view events.

Still, within the context of what could potentially be a brutal, 12-round, knock-down-drag-out fight—even just to provide a punch of patriotic uplift before it all goes down—Lovato would seem to be going kinda off-brand here.

Moreover, Lovato has ripped the pads with former UFC light heavyweight champ "Suga" Rashad Evans, who posted on Instagram, "She trains crazy hard! Hell. I thought she was training for a fight but they say that's just how she rolls."

So when it came time for the McGregor-Mayweather fight, the event organizers knew exactly who to call about a national anthem performance.

And all you closet Sonny With a Chance fans may also be fascinated to discover Lovato has repeatedly approached Glazer about getting her into the octagon for a sanctioned MMA fight. "She's brought it up to us a million times," he toldTMZ Sports. "She throws elbows better than most of the UFC guys that come in here."

The Dallas native also has an amply chronicled romantic history with MMA superstars. Between November 2016 and January of this year, she was dating former UFC and Strikeforce middleweight champion Luke Rockhold. And after they called it quits, the singer—who was named one of Time's most influential people of 2017—took up with Guilherme "Bomba" Vasconcelos, a Brazilian welterweight who currently fights with Bellator MMA.

Although the two are no longer together, in February, Lovato told Ellen DeGeneres she feared for Vasconcelos's safety every time he stepped into the ring. "It's cage fighting," she said. "It is dangerous!"
